You don't import from 2019. You TRANSFER it. You can only transfer when you first start a new blank return. So go up to FILE - NEW and it should try to find your .tax2019 file. If it doesn't find it you can browse to where you saved it. It might help to move it to your Documents and create a TurboTax sub folder. Don't try to transfer it from the flash drive. First copy it to your computer.
